2,1-BENZISOXAZOLE Chemical Properties,Uses,Production

Application

Benzisoxazole (benzoylimine) is often used as the parent nucleus of other compounds; for example, 3-methylbenzisoxazole (benzoylimine) can be used as a pharmaceutical synthesis intermediate.

Chemical Properties

CLEAR YELLOW TO BROWN-RED LIQUID

Uses

Anthranil undergoes thermal decomposition during single pulse shock-tube experiments to form aniline and cyclopentadiene carbonitrile. Surface-enhanced Raman spectrum of anthranil in activated silver colloid has been studied.

Definition

ChEBI: A benzoxazole in which the benzene ring is fused to a 1,2-oxazole ring across positions 3 and 4.
